I have one measure to repeat unspecified number of times but in order to get from pppp to p. How to notate it?
If I put repeat symbol and crescendo, it can be understood as numerous times crescendo every time the repetition begins.

Hm John, that is also quite interesting, the only problem is that I need to reach p at the end of that repeat, not in the next measure.
I think that the language barierre is the most problematic. Usin David's ‘repeat ad lib through crescendo’, or better ‘repeat ad lib through crescendo until p’ is perhaps the most exact what I want to achieve.

PS John, what is the text font you use?
PPS John, I have sent you a private message.
